MedusaLocker is one of the biggest ransomware aggregators that spreads a number of malware infections. Just like other ransomware programs, the virus is meant to encrypt PC-stored data and demand a monetary ransom in exchange for decryption software. .krlock, .L54, and .ever101 are the most recent versions published by MedusaLocker Ransomware. They are also the extensions assigned to each compromised piece. For instance, a file like 1.pdf will change to 1.pdf.krlock, 1.pdf.L54, or 1.ever101 depending on which version hacked your system. There is no real difference in which version pounced your network. All of them use a combo of AES and RSA algorithms to write secure ciphers over the data. The only aspect that varies is ransom text notes created after encryption is done. Although the content may differ but still contain more-less the same message to infected victims. You may face ransom notes named Recovery_Instructions.html, HOW_TO_RECOVER_DATA.html, or similar leading to browser pages.

There has been a lot of complaints by people unable to enter Geforce Experience, a utility developed by Nvidia to improve gaming capacity. After trying to launch, users get faced with a message stating "Something went wrong. Try rebooting your PC and then launch GeForce Experience. Error Code: 0x0003". If rebooting your system does not work out eventually, more likely there are broader reasons causing this problem. Error code 0x0003 can be related to corrupted/bugged drivers, disabled or misconfigured Nvidia services, network issues, and so forth. To find out which one of these has triggered the error, let's try each step-by-step solution presented below.

Error 0x80070141 is a tiresome problem deflating users' ability to transfer files from their phone devices. Put differently, this problem occurs whilst trying to copy Android or IOS files to your PC. Usually, it is triggered by wrong smartphone settings, lack of drivers, and other less significant reasons. Because most users are not willing to tolerate this annoying problem, we have grouped a range of solutions in the article below.

Venomous is a ransomware-type virus that puts most of the stored data under lock and demands the so-called ransom to get it back. This process is more known as file encryption as there are cryptographic ciphers applied by malware with the help of AES-256 algorithms. Besides encrypting files on the configuration level, Venomous also changes them visually. It combines original file names, victims' IDs, and .venomous extension to rename compromised data. For instance, a file like "1.pdf" will emerge as 1.pdf.FB5MMSJUD2WP.venomous at the end of encryption. Soon after this, Venomous moves next to creating a text file called SORRY-FOR-FILES.txt that stores decryption instructions. The note states all data held on your system has been infected with strong algorithms. It is also forewarned to not rename or edit encrypted files as it may cause them to break. To ensure guaranteed and corruption-free recovery of data, victims are offered to buy decryption keys stored by cybercriminals. For this, users should send their personal ID to @venomous_support via the Telegram app or contact extortionists using venomous.files@tutanota.com e-mail address. On top of that, it is also proposed to test free decryption before paying the ransom. To do this, victims are guided to open a Tor link attached to the note and upload 1 encrypted sample of data.

Errors like Microsoft Visual C++ Runtime Library are quite unpleasant to face. They diminish users' experience causing programs to fail at their setup. In other words, the error occurs whilst trying to launch an application on your PC with the following message - "This application has requested Runtime to terminate it in an unusual way". This, therefore, restricts people from seeing any further communication with the problematic app. As a rule, cyber experts tease out a couple of reasons for its appearance. Most common include graphics card issues, disfunction of Visual C++, outdated drivers, corrupted files, and malware intervention to close out this list. It is quite hard to find out which one of these leads to the corresponding issue. Thus, it is necessary to try all of the steps until you find the one solving the error. Below, you can see the set of most popular and effective solutions used to address Runtime problems.

Being part of the Dharma Ransomware family, Dharma-TOR is another malicious program that runs encryption over personal data. By committing this act, developers force victims into paying the so-called ransom. The first sign of Dharma-Tor infecting your system reflects in new file extensions. Cybercriminals assign the victim's personal ID, contact address, and .TOR extension to the end of each file. For instance, 1.pdf or any other files stored on your system will get a new look of 1.pdf.id-C279F237.[todecrypt@disroot.org].TOR, or something similar. Soon after all data becomes successfully changed, Dharma-TOR features a pop-up window along with a text file called FILES ENCRYPTED.txt, which is dropped onto the desktop. Both pop-up window and text note are meant to instruct victims through the recovery process. It is said that users should contact developers by e-mail stated in the extension with their personal ID. In case of no response, victims are guided to choose another e-mail address attached in the note. After establishing successful contact with cybercriminals, users are likely to get payment instructions to purchase decryption of data.

Users infected with Makop Ransomware will see their data blocked from regular access and changed by visual means. There are different versions used by Makop developers to spread onto victims. The only real difference between them lies in various extensions and e-mail addresses (.hinduism, .gamigin, .dev0, etc.) used to rename the encrypted files. The rest can be described as pure replication of previous Makop versions by a template. Once this virus gets settled into a PC, almost all data available will be assigned with unique victims' ID, contact e-mail, and random extension depending on which version pounced your system. For instance, a file like 1.pdf will be changed to something like this 1.pdf.[9B83AE23].[hinduism0720@tutanota.com].hinduism, or similarly with other extensions like .gamigin, .dev0, or .makop. Soon after this part of encryption gets to a close, the virus drops a text note called readme-warning.txt into each folder containing compromised data. The note lists out a number of Q&A items explaining recovery details. Users are said they have the only way to restore data - pay for decryption in Bitcoins. The payment instructions will be obtained only after establishing contact by e-mail (hinduism0720@tutanota.com, gamigin0612@tutanota.com, xdatarecovery@msgsafe.io, or other address). Likewise extensions, contact addresses are one part of the equation varying from person to person as well.

Windows 10 is nowhere next to being flawless, especially talking about the installation of updates. Since its release, users have been facing various updates errors. Windows is a complex operating system, which is less likely to ever get rid of such problems forever. A wide range of features and settings tangled up in the Windows system are more likely to meet some error for unexpected reasons. The 0x80070652 error code appears whilst installing new updates. It stops the installation processes and sometimes forces the system into a BSoD (Blue Screen of Death) crash. It is no revelation that such errors tend to appear due to damaged files, incompatibility, and configuration issues. However, sometimes users are forced to bog down deeper into resolving the issue as there are broader reasons for the appearance. Below, we will show 7 solutions in total panning from easy to more advanced methods. Make sure to follow each step precisely to not miss any important detail.
